Application filed April 19, 191?. Serial No. 163,109.

To all whom it may concern.'

Be it known that I, REGINALD IIEINZEL- MAN, a citizen of the United States, and a resident of the city oi Belleville, county of St. Clair, and State of Illinois, have invented a new and useful Improvement 1 n Spring-Catches, of Vwhich the following is a specification. Y

This invention relates to holding devices for hinged windows, particularly for small windows that are arranged to swing either on a horizontal aXis, such as transom windows, ventilators, and wind shields for automobiles, or on a vertical axis such as casement windows andthe like.

One oi" the objects of the inventionis to provide means whereby the window may be readily opened to the desired position and rmly held in its adjusted position.

Another object'l of the invention is to provide a combined hinge and device for automatically holding windows in open or partly open position. A. further object of the invention is to provide a holding device for swinging windows which are subject to vibration, particularly to windows or wind shields of automobiles where it is very difiicult to hold the window or wind shield in the desired open position, due to the constant vibration of the body of the automobile.'

The invention consists in the parts and arrangements hereinafter more fully described, reference being had to the accompanying drawings, and is more particularly dened in the claims.

In the drawings, wherein the same reference characters refer to like parts in the several views, ,Y

Figure 1 is a front elevation of a portion of a window and frame provided with a spring locking hinge, embodying my invention; Y

Fig. 2 is a vertical section taken through the window and frame on the line 2 2 in Fig. 1; and

Fig. 3 is a side view of the window and hinge shown in Fig. 1, shown in partly open position.

The locking device illustrated in the drawings is shown applied to an outwardly swinging window hinged. at the top. The window comprises a window sash 1, fitting in a window frame 2. Secured to the side Viange of the angle bracket 3 on the window sash. =The angle bracket and the notched sector are pivotally secured near their tops by a hinge pin 7 with the spring 6 between their adjacent faces. .This pin 7 also passes through the upper end ofthe spring 6, holding it in position at the top. The spring is held in position at its lower end by a pair of lugs 8 on the outwardly projecting flange of the angle bracket 3.

The spring 6 engages any one of a series of notches 9 on the inner face of the sector 5. The edges of the notches 9 are beveled to permit the spring 6 to ride out of themV when the window sash is swung by hand. rlhe spring is stitl enough to hold itself in the notches under ordinary conditions, such as vibration and wind pressure. In the construction shown in the drawings, when the sash is swung outwardly the angle bracket 3, which is secured to the sash, moves with the sash, and the free middle portion of the spring moves across the notches on the inner face of the sector 4, and comes to rest in the notch corresponding to the desired angular position of the sash.

The top notch has a square shoulder 10 whichprevents the edge of the spring from riding over it when the sash is in full open position. The sectors and angle brackets are made in rights and lefts, one of each being arranged on each side of the sash and window frame.

The invention can be applied to various types of windows and doors by merely reversing the parts, therefore I do not wish to be limited to the eXact construction shown.

I claim the following as my invention:

1. A hinge for a swinging window or the like comprising a sector 'and a second. member pivotally connected together and adapted for attachment to a window frame and a window sash respectively, and a flat cent to said sector, said sector and bracket being hinged to each other in alinement With the line about which they Window swings,

and a fiat spring held by said bracket in position to frictionally engage the notches of the sector for holding the Window against movement.

, 3.v A; spring catch for a swinging Window or thelike comprising a seetoradapted to be iXedly secured at the edge of the Window, thelinner face of said sector having inwardly projecting lugs forming .notches thereon, an

angie bracket mounted at the edge of said swinging Windowadjaoent said sectorya hat spring secured lat lts lends 4to said bracket,

Asaid spring frictionally day the free mid-die portion of said Vspring contacting fiatwise with the notches on the sector and frietionally held thereby against movement Vwhereby the Window iis heid in adjustec'i position.

4L. A combined spring catch and hinge for swinging Windows comprising two members hinged to each other, one of said members being secured to the Window frame andthe other member being secured to the swinging Window, said members having a fiat spring interposed between the faces and seen-red to one of them, one vof said members having notches arranged in a spiral curve around its hinge, the notches for the Wider open positions of the YWindow being farthest from the hinge, and the tree middle portion or" engaging said notches nearer its end remote from the. hinge as theWin'doW approaches theuil open posi-- tion.
